A while ago one of my friends mentioned to me that they don't actively remember their eurocheque card security code, but they can enter it automatically, without thinking.
That made me think about my security code and I also couldn't remember! But the thought tripped me up so much, that I couldn't let it go and the next time I had to withdraw some cash, I didn't know what to put in. I actually had to return my card and get a new one a few days later. Now I make a conscious effort to think about what I am entering.
I almost forgot my Android unlock pattern once. The phone rebooted while I was sleeping, and I was still a bit groggy when I tried to unlock it. Perhaps I fat fingered my first attempt, but then I suddenly couldn't remember what the pattern was. Fortunately I got it working on the last attempt before the phone would factory reset. As I was traveling at the time, that would have been a small disaster. Never would I have thought that this could be happening.
I put my credit card PINs and my Android pattern in my password manager after that. Still makes me wonder how I would access my secrets if I were to forget the thing I enter several times a day, every day.
